Abstract

The present invention teaches an improved method of controlling a cursor on a computer screen, without using the hand, by strapping the mouse around the patella section of the leg with a patella strap and utilizing leg muscle movement, while sitting down, to control the direction of the cursor. After manipulating the cursor by using body movement and keeping both hands on the keyboard, the programmable function keys or another hands free or appendage attached push button, motion, or voice device are used to execute a command. By eliminating the need of hand movement to move the cursor, the user is helped to prevent the development of carpal tunnel, DeQuervains tendonitis, debilitating muscle cramps, fatigue and other repeated motion related conditions.

Description

FIELD OF THE INVENTION

The present invention relates to cursor manipulation devices. More particularly, the present invention relates to hands free cursor manipulation devices.

BACKGROUND OF THE INVENTION

A computer mouse is designed to control the movement of a computer's cursor, which is a marker that points to a specific location on a computer's screen, enabling the user to access different functions within the computer. There are different methods used to connect the mouse to a computer: a cord or wire to connect from the mouse to a computer's PS/2 port or a cordless mouse, which is not physically connected to the computer, but instead uses infrared or radio waves to transmit signals to the computer.
The shortcoming of using a typical computer mouse is they are generally positioned on a user's desk top or workstation. This requires the user to continuously use one hand to operate the computer's mouse in order to control the cursor on the computer screen. Mouse manipulation requires the user to: grasp the mouse; move the arm and wrist to position the mouse, as needed, to perform a scrolling function or to activate the buttons. Because of the amount of movement required from the arm, wrist and fingers to control a conventional computer mouse, conditions, such as, carpel tunnel syndrome and tendonitis can occur from repetitive use.
Reports on the growing number of people experiencing carpal tunnel from the continuous use of a hand operated desk top mouse is prevalent in today's computerized world. One practical solution is the use of hands free devices to control a mouse cursor on a computer screen. Various attempts have been made to address the foregoing problem of carpel tunnel and other conditions resulting from the continuous use of a hand operated desk top computer mouse. For example, one prior art approach is disclosed in U.S. Pat. No. 5,841,426, as a foot operated computer mouse for controlling a computer, providing similar functions as a conventional hand operated mouse. This device is large and bulky, in order to accommodate the varying sizes of a foot to operate the cursor, therefore, would be useless and impractical in tight confined work areas.
Another example is U.S. Pat. No. 6,262,715B1, for an “ergonomic computer mouse.” This invention discloses a mouse that provides comfort for the user by maintaining the user's hand at an acute angle to the horizontal.
This invention requires the user to move an arm and wrist away from the computer keyboard to locate and grasp the disclosed mouse, therefore, preoccupying the user's hand and use of arm, wrist and finger muscles. U.S. Pat. No. 6,154,199 discloses a glove-like article that contains a tracking ball on the side of the index finger for manipulation by the user's thumb, with mouse buttons located on the palm of the glove-like article, which are controlled by the user's fingers. U.S. Pat. No. 6,850,224 discloses a “wearable ergonomic computer mouse,” designed to be worn on the hand of a computer user. Flexible adjustment straps are used to attach an electronic base to the user's hand, for transmitting electrical signals to the computer system. Both of these inventions require the use of a user's fingers or hand to either position the cursor or to operate the mouse buttons, which may cause injuries and muscle strains from repetitive movement. In addition, one of the user's hands is required to operate the movement of the computer's cursor.
Therefore, there remains a need for an improved method to operate a computer mouse effectively, hands-free, while eliminating the repetitive strain on the user's arm, wrist and fingers that may cause carpel tunnel syndrome, tendonitis, or muscle pain and cramping.

SUMMARY OF THE INVENTION

A knee operated computer mouse is strapped and worn around the user's patella, below the knee, or any section of the leg, to control the movement and direction of one or multiple cursors on a computer screen, without the use of a hand, by utilizing leg muscle movement while sitting down, thus preventing the development of carpal tunnel syndrome, DeQuervains tendonitis and other conditions.
Powered by plugging into a USB port, alternative power may also be used, such as, a rechargeable battery source contained within the mouse component compartment. The user can control multiple functions on the computer screen with the use of mouse software. The mouse software enables the user to see a display of the accelerometer's functions to enable the user to personalize and navigate the cursor precisely. The mouse software can be upgraded to enable the user to control one or more cursors on multiple computer screens simultaneously, whether the user is wearing one knee operated computer mouse on the right patella, or is also wearing an additional knee operated computer mouse on the left patella to provide independent control of multiple cursors. To execute a command that the cursor is on/over, the user presses the programmable function keys on the keyboard, or another hands free or appendage attached push button, motion, or voice activated device.
A connector, which can be a cord, infrared light, USB or Bluetooth, is contained within the mouse component compartment, and allows the computer to read the information the mouse transmits to the computer. The mouse component is attached to a patella strap, which wraps securely around the patella section of the leg, just below the knee, to support the mouse component to the leg. A tilting scroll wheel is contained within the mouse component compartment to enable the mouse to control the directional functions of the mouse cursor on a desk top when detached from the patella strap.
The accelerometer is contained within the mouse component compartment and acts with a gyroscope, enabling the user to manipulate the cursor on the computer screen by using leg motion, which transmits a signal to a receiver plugged into a USB port. An encoder chip is contained within the mouse component compartment to convert movement into digital signals. A function LED button, contained within the mouse component compartment allows the mouse's software to be upgraded, reset, and to program the keyboard's function keys.
To resolve the drawbacks associated with the prior art, it is an object of the present invention to provide computer users with an improved, hands free computer mouse device that enables the user to control a cursor and movement on a computer screen, without using the hand, by strapping the mouse around the patella section of the leg with a patella strap and utilizing leg muscle movement, while sitting down, to control the direction of the cursor. Selection and execution of the mouse commands are completed by pressing the programmable function keys on the keyboard of the user so that the user never has to remove their hands from the keyboard.
It is another object of the present invention to provide a knee operated computer mouse with software to enable the user to control multiple functions on the computer screen and see all information displayed, including the accelerometer's functions, to enable the user to navigate the cursor precisely on the computer screen before executing commands using programmable function keys on the keyboard.
It is a further object of the present invention to provide a knee operated mouse that attaches to a patella strap, which wraps securely around the patella section of the leg, just below the knee, to support the mouse component to the leg.
It is still a further object of the present invention to provide a knee operated computer mouse with a tilting scroll wheel to enable the mouse to control the directional functions of the mouse cursor on a desk top when detached from the patella strap. A still further object of the present invention is to provide a knee operated mouse that helps prevent the development of carpal tunnel, muscle cramps, DeQuervains tendonitis and other conditions.
These and additional objects of the present inventions may be determined from a review of the instant disclosure, disclosing a knee operated computer mouse for controlling a cursor and movement on a computer screen, without using the hand, by strapping the mouse around the patella section of the leg with a patella strap and utilizing leg muscle movement, while sitting down, to control the direction of the cursor. Once the cursor is over the desired selection, execution of the mouse commands are completed by pressing the programmable function keys on the keyboard of the user. The knee operated mouse is powered by plugging into a USB port, or using alternative power, such as, a rechargeable battery source, being contained within the mouse component compartment.
Other objects, advantages and features of the present invention will become apparent upon a consideration of the following detailed description, when taken in conjunction with the accompanying drawings. The brief description sets forth broadly, the more important features of the present disclosure so that the detailed description that follows may be better understood, and so that the present contributions to the art may be better appreciated.
